Bosch provides a cross reference chart for the Torch. This chart should give all of the various cross references for the Torch series including the F 7 RTC plugs.
If you have no spark on the 1991 Subaru Legacy, you should check the spark plugs and spark plug wires for replacement. You should also check the battery and ignition for replacement.
